I am reading a classical Weir and Cockerham 1984 paper about Fst estimation. At the beginning (first page, right column), they define 3 statistics.
$F$ is the correlation of genes within individuals ...

There have been papers discussing this, and whether the abstinence period should be 1 week, 2 weeks or other [1, 2]. Some think the time to maximum ejaculation volume is even longer than this.

I have morphometric measurements for a trait across various animal taxa, and would like to study the relationship between the size of this trait, and the animals' body size. In theory, I can account ...

I want to calculate the Jaccard index between two compounds. What is the algorithm? I have searched for it, it just gives the formula but how to apply it on compounds is not known to me. Can you help?
...

The simplest description of the difference between these two approaches that I have found are on this site who summarise the difference as:
Mechanistic model: a hypothesized relationship between the ...

MEN 2A is a dominant inherited disease caused by a mutation in the RET proto-oncogene.
The probability of being sick when you have the mutation of the RET proto-oncogene varies with age and is assumed ...

What Information am I looking for?
Think about a tree that is sending pollen all over the place. Because of wind, most pollen grain will go toward one direction. Imagine, we split the 2D area around ...

In papers reporting a relative quantification of gene expression by RTPCR, I often see a bar chart with mean ± standard error or deviation, with the deviation belonging to biological replicates. This ...

I have a data set with expression levels of a list of genes, measured in replicate at two different time points between two groups; a control group and a disease group.
I want to identify the changes ...

Suppose I want to find out the number of herbivores in different kinds of trees, and also compare the numbers between day and night. How would this kind of study be run in practice? It easy to think ...

Ordinal response variables show up often in biology, but I'm not sure how they are best analysed. Some examples are qualitative assessments (little, many, a lot) or risk assessments (low risk, medium ...

There is a dataset that contains body mass ($x$) and metabolic rate ($y$) from many different organisms. It is common to fit the data to the model of the form $y=ax^b$ and estimate the parameters $a$ ...

For the problem below I am aware of the statistics involved but just can't get my finger around the following:
In biology we use qPCR to measure gene expression or basically number of mRNA copies. It ...

Recently the UK government suggested that all adults over the age of 50, without exception, would benefit from taking statins.
I have an elderly female relative who may, or may not have had a minor ...

I have a question about cancer cure statistics. Many of the cancer literature or databases I have come across speak about 5 year or 10 year survival rates. In this case survival means that the patient ...

We have gene expression data (Affimetrix mRNA gene expression results) for several cell lines, over a set of genes. Our goal would be to be able to compare relative gene expression for genes over the ...

This is my first question here, so I apologize for all mistakes I could have possibly made.
I'm a high school student in East-Central Europe and I need to complete some research for a biology contest ...

According to Knudson hypothesis, cancer mutations accumulate in order. Statistics says, that cancer probability increases as sixth order of age, which may mean six consequential steps to cancer.
But, ...

I am in great need of help in order to infer the statistical hypothesis tests performed in an old paper. However I need to make some reasonable guesses only from the abstract of the paper since the ...

Approximately, how many families have been identified?
I've often often come across figures for the total number of species on Earth. Recently, I found myself wondering about the encompassing ranks ...

I'm at the moment analyzing cytokine array data. The available material on the statistical analysis of these data is more than unsatisfactory. Since a lot of effort is being made in the analysis of ...

I have been reading with fascination about the several molecular- and cellular-scale mechanisms and structural changes that underlie what we refer to as long-term plasticity. For instance, [1], [2], ...
